Figure 17.16. Example for the “Pixelize” filter

Original

“Pixelize” applied

The Pixelize filter renders the image using large color blocks. It is
very similar to the effect seen on television when obscuring a
criminal during trial. It is used for the “Abraham Lincoln
effect”: see [BACH04].

2.6.2. Activate the filter

You can find this filter in the image menu through
Filters → Blur → Pixelise…

2.6.3. Options

Figure 17.17. “Pixelize” filter options

Pixel width, Pixel height

Here you can set the desired width and height of the blocks.

By default, width and height are linked, indicated by the chain
symbol next to the input boxes. If you want to set width and
height separately, click on that chain symbol to unlink them.

Using the unit selection box you can select the unit of measure
for height and width.
